WTF is an 02 Heater Malfunction??

i had my SAT test this morning, yes im still in high school, and i was sitting in the parking lot talking to some girl from the test class. got her number went to leave, looked down engine was warm, oil pressure was normal so i just kicked the clutch in tached it up and dumped itlittle smoke a little sideways just to show off a bit,

going down the street i look down again, Service Engine Soon, glaring in my face

take it to auto zone, argue with the guy about the plug i need for the scanner, he says OBD I i say OBD II, he says w/e im going to laugh when im right. im like sure dude, go jump off a cliff. get it hooked up read the code and it saw i have 2

P0161 O2 Heater Malfunction (Bank 2 Sensor 2)

then i scroll down some more, same code same bank same senser

im like sure, clear them and drive off, the light hasnt come back on and the car is definatly running good, so wtf caused this?

 

Here is some detailed diagnostic information about that error code. Check the O2 fuses, and it could be a bad O2 sensor.

 

thanks
